No Mapping Flat Code

The differences between Geraldinho and the original Teddy Boy are:

  1. ^ The two logos are the same size (17 x 4 tiles), but the Geraldinho logo uses more unique tiles (68 to Teddy Boy's 29). Thus the name table data is changed in-place, but the tile data is not - the (2bpp uncompressed) Geraldinho tiles are all added at the end of the ROM, in space which is unused in Teddy Boy.
  2. ^ The maximum possible number of lives is therefore 7 - this number is large enough to cause problems on the screens between levels.
